# 手动定位
在特殊情况下，你可能想手动定位下拉菜单。比如在一块区域右击以弹出下拉菜单。
```html
<div style="width: 200px; height: 200px; background-color: rgba(0, 128, 0, .5);" @contextmenu="handleContextMenu">
  右击
</div>
<n-dropdown
  placement="bottom-start"
  trigger="manual"
  manually-positioned
  @select="handleSelect"
  @blur="handleBlur"
  :x="x"
  :y="y"
  v-model="showDropdown"
>

    }
  }
